Car would not crank over

It sounds like you have a bad starter motor but to be sure here is a guide to help confirm the failure.

and

Please run down these guides and report back and check out the diagrams below

Is the starter engaging at all? Have you checked the starter relay?

Is the vehicle equipped with the Passive Anti-Theft System (PATS)? Is the anti-theft light flashing? If so, you may want to start there by having the system inspected by a reputable dealer.

If you believe that the anti-theft system is not at fault, I would re-check battery and ground connections - closely inspect all cables for corrosion first. Perform resistance - or preferably - voltage drop tests to determine high resistance in the cables.

Hello

To better assist you please tell me your engine size in liter and the 8th digit of your VIN.

So currently, when you turn the key on to start all of the dash lights come on, but the engine makes NO sound at all... Just dash lights?

Please go to Auto Zone (AZ) or O'Reilly's (OR) and use their tool check out program and get the code scanner. Check your codes, if you find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that.

Hello

Thanks for the update.

If the truck just dies like someone turned the light switch off and you tried to start it and nothing happens at all, that is the engine doesn't turn at all..... The dash lights are on but the engine is not turning....... The first place I would check is the ignition switch

Now if it had been running and you stopped, shut it off, came back and tried to start it and got lights on the dash again but nothing turns over, then I would throw the starter and relay into the mix to check.

Though it is running right now you could still check fuses 12 and 23 in the battery junction box under the hood and fuse 29 in the central junction box left side of the dash. Use an ohm meter though.

You could try this to see..... Though you have a newer car if may work.

Sometimes to check for a faulty ignition switch you can: Slowly turn ignition switch from ACC to ON, does the dash lights flickers or goes off? (YES?) Slowly turn to START, does the light flickers or goes off? ( YES ) When cranking the starter, is the battery charge light ON all the time? ( NO ) If answers are as in the brackets, the ignition switch is possible bad. Please let me know what happens though.

Hello Again,

I was searching through the TSBs for your car and came across this....... It may have something to do with your problem...

For now I would go over all my wiring and make sure all of my connections are clean and secure. The battery, starter, alternator etc.....

Hope this helps.

Have you tried replacing the relay?

You could possibly have an intermittent problem with the starter.

I would check these too.

Starter motor relay.
Ignition switch.
Anti-theft system.
Circuitry.

I hope this helped.

Good Luck;
Rick

The transmission wouldn't cause the problem you described. Also, the battery cable that goes to the starter should be the positive not the neg. The neg grounds to the engine block. Check to make sure you don't have things mixed up and make sure to replace the bad cable. As far as the engine, however, if you can't turn it by hand, chances are the engine is locked up.

If the theft light is flashing the security system has tripped and it shuts of fuel and spark so the engine will not run. Check to be sure you have the correct key. If it is okay the anti-theft module may be faulty. A good scan tool can read the system and show you what the issue is. I am not talking about the code readers like they use for free at the parts stores but a dealer machine.
